Cheers guys!

I drive a audi S4 B5 sportec stage 3+ tuned engine. I took the engine from a rammed car, and replaced parts that i needed to from my original engine. The thing is that he should gain near 460 horsepower, but he doesn't. In lower rpms he runs beautiful, but the 100-200 takes almost 12 seconds, and if i push him hard, he goes in limp mode around 220 kmh.

When i got rid of leaks, he throw me a bank 2 egt code, after i raplaced that one he threw a bank 1 code, so I've replaced that one as well.

Yesterday I've pushed the car, and now he threw code of EGT bank 1 again, but beside that he threw charge pressure control: negative deviation (had that before) and MAF sensor signal too high.

DV's are ok (they hold pressure)
I can replace N75 (have a spare one, but don't think it would help)

Is there any other part of the car that can relate to those 3 codes mentioned above?

Clogged intercoolers, bad catalytic converter, or something?

Thank you!
